Hello Danny, I don't consider either these facts as failures neither as unspoken. They are limitations, borders of the online world with the offline one, which we will eventually cross (with the help of technology!)

There are many people who says building networks its a kind of spam..What about if you build a great network, with really good content and each site focus exactly to give an answer to the users.

We have to be far from networks or we should make networks with high quality of content, desing, structure and of course convertible?

And dont you think its harder focus your efforts on.. lest say 100 sites instead sent always your best links with the tops anchor text to your main site and try to get this long tail with quality content , link baiting, internal links and using always the correct meta title to get this long tail at the same time your are reaching great positions for best keywords on serps and building and authority wiches give you the chance to rank well with your long tail seo posts/landing pages?
